Cannabis has been consistently used to treat pain since the beginning of its medicinal history. Even today, the most common reported use of medical cannabis is for pain relief, and support for this is not only anecdotal, as there’s a large body of evidence supporting this claim. Although cannabis is helpful to many who suffer from pain, there are still many limitations to using it as a pain medication. The most obvious problem is that cannabis causes a well-known “high” feeling. This effect is not necessarily negative, yet it may not be ideal when attempting to relieve pain symptoms. Not only does cannabis get you “high” but it can reduce motor control, attention and can potentially cause memory problems, anxiety, confusion and even panic for some users. These side effects greatly limit the ability of cannabis to be used as a pain medication for many people. Many of the effects mentioned are caused by a compound called THC, which is short for Δ9-tetrahydrocannabinol. Thankfully, there are over 100 other substances in cannabis that are very promising for the development of better pain relief treatments.
One of these other substances is cannabidiol, or CBD (cannabis’ other main component) which has gained a lot of attention lately for its potential as a treatment for conditions like epilepsy, multiple sclerosis, anxiety and pain. CBD does not cause a “high” like THC making it a more realistic option as a pain reliever. Less well known is a compound called CBDA, or cannabidiolic acid, which is the precursor to CBD. This means that CBDA is found in the fresh cannabis plant and is converted to CBD after drying or heating of the plant. Scientists believe that this compound also has similar effects to CBD. So why would we be interested in this compound if we already know that CBD can reduce pain? Well, research shows that CBDA is a lot more potent than CBD. For example, CBDA is able to reduce nausea at a dose that is 100-1000 times smaller than an effective dose of CBD.
Because of the strength of CBDA in comparison to CBD, researchers in Dr. Linda Parker’s lab at the University of Guelph tested whether it could reduce pain caused by inflammation. They found that CBDA is able to reduce pain and swelling when given to rats. In fact, CBDA reduced pain and inflammation in rats at a dose that was much lower than that of CBD, indicating that this compound can be even more effective at relieving pain than CBD.
It is well known in the science community that the two main molecules in cannabis – CBD and THC – can work together to produce some of the effects caused by cannabis. Because of this, another experiment was conducted to see if CBDA can work with THC to reduce pain. To study this, THC and CBDA were combined at very low doses that, when given alone, are not able to reduce pain. When combining these low doses of THC and CBDA, both pain and inflammation were reduced. This finding is exciting because as mentioned, the use of THC for pain management is not ideal because of its negative side effects but combining smaller amounts of this THC with other drugs like CBDA might be able to decrease its side effects while still taking advantage of its pain-relieving effects.
The findings from this study are very promising for better understanding how different compounds in the cannabis plant can be used to alleviate pain. Many of the medications prescribed for pain today are opioids which have unwanted side effects and are highly addictive, contributing to the opioid epidemic currently happening in the United States. There is a great need to develop better and safer medication for the management of pain, and compounds from the cannabis plant may just be the solution.

Hope this pans out. I have been using CBD for pain relief from various orthopedic injuries for years. It has really helped take the “edge” off, in particular for morning pain for me. I have often felt as I get older, I will eventually break down more and need opioids at some point in my life. But the longer I can delay that the better for quality of life. Some like this is refreshing and gives me hope with CBDA.
Great article. Had no idea. Thanks!
I am a small craft cbd processer and I have started processing cbda and adding it to my cbd product. I use a lipid ,lipid infusion of MCT oil process with a small licithin base, using low temp to infuse. The feedback i am getting plus what I am experiencing with myself and with my own dogs is fantastic. I have been able to redusce what I take and give my dogs getting even better results. My customers say that it works better than other plain cbd products that they have used. I think that CBDA will be the new Buzz word.
How do i turn my CBD flower buds to cbda oil
Hello Vicky,
I am curious about how you are giving the cbda to your dog? I have an 18 yr old Brussels Griffon mix and I want to help her feel as good as she can and live healthfully as long as possible. She doesn’t eat much and giving her oral supplements has always been a challenge. Is it safe for a dog that weighs less than 10 lbs? Thanks
I have recently started to consume (eat) the younger leaves on my organically grown(soil and water no additives) cannabis plants. I have noticed I have had no stomach issues lately, and no inflammation, I also use CBD when i am taking chemo almost no nausea as compared to anything I have ever ben prescribed for nausea, . I typically soak them in cold water with a little apple cider vinegar to make sure their is no bacteria, from all the years of using full plant extract CBD the taste is fine with me. Throw them in a sald or low heat and season the way you would spinach.
I have been fighting Multiple Myeloma for 4 years now and am either very lucky or the addition of CBD has allowed me to be lesion free, not cancer free but this is a cancer that usually affects the bones as it is a plasma cell disorder originating in the bone marrow.
I continue to be treated with chemo and novel agents and trust my doctors, but adding CBD and now CBDA in its raw form has allowed me to feel pretty healthy aside from living with cancer,
